Abstract (en)
[origin: WO8500614A1] Process for preparing low- or non-dusting substantially completely non-volatile metal pigment compositions by forming a coherent paste comprising an organic binder medium, an organic liquid vehicle and metal pigment, in powder or flake form, the paste being formed by mixing a first component comprising the organic binder medium and a second component comprising metal pigment with either or both of the first and second components comprising organic liquid vehicle and the paste containing from 1 to 70 percent, preferably from 3 to 45 percent, of the organic binder medium based on the weight of the metal pigment, and removing substantially all of the organic liquid vehicle(s) from the coherent paste, optionally after sub-dividing the coherent paste into particles, such as pellets, tablets or granules. The resulting solid metal pigment composition comprises metal pigment particles dispersed in a matrix of the organic binder material.
